It is not known which supplemental imaging technique is most beneficial for women with dense breasts attending breast screening. This study compares abbreviated MRI, automated whole breast ultrasound (ABUS), and contrast-enhanced mammography versus standard of care in women with dense breasts and a negative mammogram. We report on interim results from the first round of supplemental imaging.

ACURATE neo2 is an open-cell, supra-annular, self-expanding transcatheter heart valve that is commercially available in over 50 countries but has not previously been evaluated in a randomised trial. ACURATE-IDE aimed to prospectively evaluate the safety and efficacy of transcatheter aortic valve replacement (TAVR) with the ACURATE neo2 valve compared with commercially available valves for the treatment of severe symptomatic aortic stenosis.

The Lancet Commission on diagnostics made recommendations for ten topics: national strategy (including national essential diagnostics lists), access in primary care, workforce, regulatory framework, national financing, affordability, appropriate use of technology, needs in conflict or fragile situations, advocacy, and an international alliance with oversight capabilities. Since 2021, progress in these areas has benefitted greatly from the adoption of a World Health Assembly resolution on diagnostics and the work of a broad coalition, as assessed by literature surveys by subject matter experts, quantitative findings (where feasible), and an anonymous survey of knowledgeable and engaged individuals. Greater progress was observed where there was political will and the production of diagnostics coincided with industrial policy goals, also in areas where changing the legal and health policy frameworks was involved. Progress was slower on recommendations with substantial resource implications (eg, labour force, affordability, and diagnostics for conflict situations). It is expected that the Global Diagnostics Coalition will consolidate and accelerate progress.

Genetic studies have established angiopoietin-related protein 4 (ANGPTL4) as a key regulator of triglyceride metabolism and a promising target to reduce atherosclerotic cardiovascular disease (ASCVD) risk beyond traditional risk factors. Human ANGPTL4 loss-of-function shows no adverse consequences and is associated with reduced triglycerides and remnant cholesterol, and a reduced risk of type 2 diabetes and ASCVD. Nonetheless, development of ANGPTL4 inhibitors has been delayed due to adverse findings in ANGPTL4-knockout mice fed a high saturated fat diet, including lipid accumulation in mesenteric lymph nodes, systemic inflammation, adverse clinical signs, and reduced survival. We previously reported the development and preclinical characterisation of MAR001, an ANGPTL4 inhibitory antibody. Here, we report a comprehensive safety assessment of ANGPTL4 inhibition, including novel analysis of genetic ANGPTL4 loss on mesenteric lymph node architecture in humans and two early-phase clinical trials.

One in five of the population lives with chronic pain. Psychological interventions for pain reveal core principles that can be used to create opportunities for chronic pain self-management in primary practice, across health-care settings, and at home. We highlight the different types of chronic pain and illustrate the psychoneurobiological mechanisms involved. We review core principles for psychological pain management, evaluate the evidence, and illustrate the underlying neurobiology involved. We provide practical advice for how to facilitate pain self-management in clinical practice. Finally, we discuss scientific caveats and practical obstacles to improvement, suggesting possible pathways to implementation.
